This new and expanded version of the second edition has been designed to assist psychologists in identifying those software packages that best fit their needs. The directory provides impartial, non-evaluative summaries of over 800 software packages, allowing academics and clinicians to choose the software they need. The volume is divided into four sections: academic software - appropriate for use in psychology instruction; psychological testing software - for use in testing; other clinical software - for use in clinical practice (other than testing); and statistics and research software - for data analysis and presentation. Several indices are provided for ease of use. Each software listing is standardised and provides complete information on which to base the selection and purchasing decision.
